Let's divide 66628186 by 87
We want to figure out the number of times 66628186 can be divided by 87.

Moving on to step 1:
The number 87 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 87

On to step 2:
87 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 87

Step 3:
87 can be fit into 666 7 times, resulting in a remainder of 57.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 57 after subtracting 609 from 666.
Grab the next digit (2) from the dividend, add it to 57, then carry on: 572 / 87

On to step 4:
87 can be fit into 572 6 times, resulting in a remainder of 50.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 522 from 572 to get 50.
Include the next digit (8) from the dividend after 50, then repeat: 508 / 87

Moving on to step 5:
When dividing 508 by 87, we get 5 with a remainder of 73.
Write down 5 as next digit of the result. 
Result so far: 765.0
Subtract 435 from 508 to get 73.
Include the next digit (1) from the dividend after 73, then repeat: 731 / 87

Advancing to step 6:
The number 87 fits into 731 8 times, leaving a remainder of 35.
The next digit of our result is 8. 
Result so far: 7658.0
If we take 696 away from 731, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 87

Advancing to step 7:
87 can be fit into 358 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 76584.0
If we take 348 away from 358, we end up with 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 87

On to step 8:
The number 87 fits into 106 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 765841.0
The remainder is 19 after subtracting 87 from 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
If we divide 190 by 87, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 765841.2
If we take 174 away from 190, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
If we divide 160 by 87, we get 1 and a remainder of 73.
The next digit of our result is 1. 
Result so far: 765841.21
Deduct 87 from 160 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
The number 87 fits into 730 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 765841.218
Subtract 696 from 730 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
87 can be fit into 340 3 times, resulting in a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 765841.2183
The remainder is 79 after subtracting 261 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 13:
When dividing 790 by 87, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 765841.21839
If we subtract 783 from 790, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 14:
87 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 765841.21839
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
If we divide 700 by 87, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 765841.2183908
If we subtract 696 from 700, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 16:
87 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 765841.2183908
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 765841.2183908 with a remainder of 4e-08.
